DIAMOND ENGINEERING - DCP252 - 2-axis EL/AZ positioner for radar module calibration

ANTENNA MEASUREMENT SYSTEMS & PRODUCTS

Diamond Engineering Series of Dual-Axis

Precision Positioners
The DCP252A is a precision 2-axis EL/AZ positioner primarily designed for radar module calibration

Diamond Engineering DCP-252A Dual-Axis Precision Positioner

The DCP252A is a precision 2-axis EL/AZ positioner primarily designed for radar module calibration. AZ and EL stages are stepper motor-powered worm-gear tables with 0.025 degree native resolution. Each axis has a home sensor which can be used to set pre-calibrated home positions. A high capacity tripod provides stability and increases weight capacity for the positioner.

 

Key Features and Functions

2D & 3D Spherical Measurements (AZ over EL, EL over AZ, XYZ planes and more)

Far Field Parameters (gain, beamwidth, efficiency, directivity, polarization, isolation, and more)

OTA Measurements (TRP/TIS)

Phase Center Measurements

Spherical Near Field (optional)

 

Highlights

Dual rotary joints

Multiple configuration options

Ultra-high precision (up to 0.02º)

Ideal for most antennas
